International Comfort Products C8MPV100J20B1 Limit Switch
Limit switches were created because if the air is too cool inside the furnace to begin with, the you will lose all the heat as the air flows through the ducts. A normal limit switch is a switch in the air handler that can determine if and when the air is warm enough for the blower to be activated.
What are some indications that my main limit switch is almost going bad?
- The International Comfort Products system is beginning to runs spotty on a regular basis
- The heating and cooling system will not begin the ignition sequence or will not stay running for any length of time
